Contact Sensor Data Provision for Consent-Based Emotion Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emotion analysis systems either acquire and analyze user data without permission, causing discomfort, or require users to wear wearable devices, leading to feelings of strangeness and resistance.
Innovation Solution
A system where a sensor with a contact surface is used to measure physical quantities indicating contact with the user's body surface, allowing users to approve the condition for data provision, with an estimation unit determining contact state and a provision unit providing data only when consent is given, mimicking the experience of applying a sticker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user data is acquired and analyzed without permission, then emotion analysis capability is improved, but user comfort and privacy protection deteriorate
Solution Approach 1:
The system obtains user consent before acquiring and analyzing emotion data. The consent screen is displayed in advance, explaining what data will be collected and how it will be used, allowing users to make informed decisions about their privacy before the analysis begins.
Solution Approach 2:
The system provides feedback to users about their emotion analysis results through the terminal device. This transparent feedback mechanism builds user trust by showing them the actual analysis outcomes, demonstrating that their data is being used as explained and allowing them to understand the purpose and accuracy of the collection.
2Measurement precision
If wearable terminals are required for emotion analysis, then measurement capability is improved, but user acceptance and ease of operation deteriorate
Solution Approach 1:
The system is designed to work with multiple types of terminals including smartphones, tablets, and computers without requiring specialized wearable devices. The emotion analysis functionality is made universal across different common devices that users already possess, eliminating the need for additional wearable equipment.
Solution Approach 2:
Instead of requiring users to wear specialized sensors, the system uses the existing cameras and microphones in common terminals to capture facial expressions and voice tones. These existing device capabilities are utilized as substitutes for dedicated wearable emotion sensing equipment.
3Productivity
If sensor data is provided to other entities without contact verification, then data provision speed is improved, but data accuracy and reliability deteriorate
Solution Approach 1:
The system performs contact state estimation before providing sensor data to other entities. The estimation unit analyzes the physical quantity data to determine whether proper contact has been made, and only after this verification does the provision unit transfer the data, ensuring both speed and reliability.
Solution Approach 2:
The estimation unit automatically analyzes the physical quantity data from the sensor to determine contact state without requiring manual verification. This self-service mechanism quickly assesses whether the sensor is properly contacted with the user, enabling automatic data provision decisions that maintain both speed and accuracy.

AI summary
This provision system includes: a presentation unit configured to present, to a user, a fact that contacting of a sensor with a body surface of the user serves as a condition for permission to provide a physical quantity to another entity other than the user, the sensor having a contact surface and being configured to measure the physical quantity, the physical quantity indicating a degree of change in a surface with which the contact surface contacts; an estimation unit configured to estimate a contact state of the sensor with the body surface on the basis of the physical quantity; and a provision unit configured to start providing the physical quantity to the other entity, on the basis of an estimation result for the contact state by the estimation unit.
